One of the themes I have been hammering away at since I starting writing about breathing is outside influences. Outside influences are things like your head/spinal relationship, erroneous beliefs, bodymapping delusions and fairytales. 

Fairytales?

Yes, like the "upper jaw" - which is about as existent as rabbit horns.

Golfers are warned never to change their swing.

And Musicians are cautious changing their embouchure –  the way you pass air into any wind instrument depends on more than your lips, breath and instrument.

Any Professional that relies on skilful movements to accomplish their technique understands the difficulty in readjusting a skill set that began at an early age through the instruction and intuitive mimicking of others.

There are many sad stories of professionals who tried to change their technique and ended up worse than when they started. 

Why is this?

It's a weird question; I'll give you that. (the Subject line silly)

Alexander put it another way, which helps make sense of it:

"Everyone wants to be right, but no one stops to consider if their idea of right is right."

This is true all over your life. A person can be with their partner for years, then one day wake up and wonder:

"Do I really love him?"

Wait.

All these years and NOW you're asking!? 

If you still don't know that, how do you know that you know ANYTHING?
